I think I am experiencing the same, or similar, problem of multiple different files of data for the same participant. We identified our participants by asking them to input the last 4 digits of their phone number, and within the final data we found certain numbers had 6 or more files. While duplicated phone numbers are certainly possible, the number of duplicates recorded was improbable.
Is anyone experiencing a similar problem and have any suggestions for how to fix it or decrease the number of duplicates?
Thanks so much, have a great day!
